Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4 of the specification, in an embodiment of the present invention, a belt board grinding machine is provided, in which a feeding and conveying line reel group 100, a receiving and conveying line reel group 200, and an output belt assembly 400 are sequentially disposed along a conveying direction of a PCB soft board, two grinding brushes 300 are disposed in the receiving and conveying line reel group 200, and an upper belt assembly 500 corresponding to the receiving and conveying line reel group 200 and the grinding brushes 300 is disposed above the receiving and conveying line reel group 200.
An upper conveying belt is wrapped on the upper belt assembly 500, a first white brush roller 710 of a first white brush 710 roller is arranged on the discharge side of the upper conveying belt, and the first white brush roller 710 of the first white brush 710 roller is arranged below the discharge side of the upper conveying belt along the rotation direction of the upper conveying belt and is in contact with the upper conveying belt.
During grinding, the PCB soft board 900 is conveyed into the material bearing conveying line windlass group 200 through the material feeding conveying line windlass group 100, then the PCB soft board 900 is brought into a grinding space formed by the upper belt assembly 500 and the grinding brush 300 through the upper belt assembly 500, the lower surface of the PCB soft board 900 is ground through the grinding brush 300, and in the grinding process, a spraying system in the machine sprays cleaning water to the grinding brush 300 to clean the residual materials on the grinding brush 300.
When the PCB flexible board 900 is carried by the upper conveyor belt of the upper belt assembly 500 to rotate together, the needle-shaped bristles on the surface of the first bristle brush roller 710 scrape the PCB flexible board 900 adsorbed on the upper conveyor belt, so that the PCB flexible board 900 is separated from the upper conveyor belt, falls on the conveyor belt of the discharging belt assembly 400, and is discharged by the discharging belt assembly 400.
Compared with the prior art, the utility model can effectively avoid the problem of clamping and folding plates caused by rolling plates when the PCB soft board 900 is sent out from the upper belt assembly 500, and improve the stability of the belt type board grinding machine.
